Application April 17, 1948, Serial No. 21,701

1 Claim.

This invention relates to woven fabrics and refers more particularly tofabrics containing plastic threads.

An obiect of the present invention is the provision of a fabric which isornamental and most effective in appearance and which has excellentdurability and wear-resisting qualities.

Another object of the present invention is the provision of a wovenfabric which can be conveniently utilized for curtains and table covers,and as a covering for various articles of furniture, including seats andcushions used in various vehicles.

A still further object of the present invention is to utilize theexcellent qualities of vinylidene chloride for the manufacture offabrics having an ornamental appearance and excellent wear resistingqualities.

Other objects of the present invention will become apparent in thecourse of the following specification.

The objects of the present invention may be realized through theprovision of a woven fabric consisting of mixtures of synthetic andplastic threads.

In accordance with the preferred embodiment of the invention, the warpconsists of a mixture of vinylidene chloride such as Saran in conjunction with rayon, acetate or cuprammonium rayon yarn while the fillingconsists solely of vinylidene chloride.

The invention will appear more clearly from the following detaileddescription when taken in connection with the accompanying drawingshowing by way of example a preferred embodiment of the inventive idea.

The single figure of the drawing illustrates diagrammatically in aconventional manner the construction of a fabric of this invention.

The figure shows a warp consisting of a sequence of rayon threads I andvinylidene chloride threads 2 and a filling 3 consisting solely ofvinylidene chloride threads.

The following are a number of examples of fabrics made in accordancewith the principles of the present invention. These examples are givenby way of illustration and it is obvious that various changes may bemade in either the warp or the filling of the fabrics.

Example 1 The warp consists of vinylidene chloride threads and rayonthreads. The vinylidene chloride thread has a diameter of 0.01" to0.012" While the rayon thread has 900 deniers to 1100 deniers and may benatural or dyed. The warp has 40 ends of rayon to the inch and 20 endsof vinylidene chloride to the inch arranged in groups of 8 ends of rayonnext to 4 ends of vinylidene chloride thread. The filling consistssolely of a vinylidene chloride thread having a diameter of 0.01" to0.012 and 34 to 44 picks per inch.

The weave may be a 4 x 4 twill weave with two in a shed.

The fabric may be made by two warp beams both drawn in a loom togetherand three or four shuttles may be used. The warp is drawn in two in eachheddle eye.

The fabric thus produced is subjected to a stiff sizing and is mostsuitable for dyeing. On the other hand, vinylidene chloride threads mayhave the required coloring incorporated therein at the time of thedyeing.

Example 2 The warp consists of vinylidene chloride threads as describedabove while the filling consists of a mixture of plastic and rayonthreads, particularly of the type described in Example 1.

Example 3 Both warp and filling consist of mixtures of plastic and rayonthreads, particularly of the type described in Example 1.

Furthermore, fabrics may be produced consisting of various mixtures ofsynthetic and plastic materials and Warp and filling.

It was found that in a fabric made in accordance with the presentinvention, the advantageous qualities of vinylidene chloride are particularly enhanced by tis use in the form of threads woven into a fabric.The fabric is quite light in weight and yet it is most suitable for useas an outer covering for articles of furniture, table I covers orcurtains. The fabric has excellent moisture resistance and takes a presseasily.

The important characteristic feature of the fabric is that it has thestrength and beauty of vinylidene chloride while avoiding the defects ofthis material. The fabric has low shrinkage characteristics and is mostdurable; it may have any suitable finish and be provided with abeautiful lustre.

Thus, a fabric made in accordance with the principles of the presentinvention has unusual properties and appearance and is particularlysuitable for articles subjected to heavy wear, such as furniturecoverings. The fabric may be pressed to a sharp crease yet will not mussor wrinkle at ordinary temperatures. Vinylidene 3 chloride used in thepresent invention consists, preferably, of extruded oriented supercooledstrand material made by the Dow Chemical Company under the name Saran.It is apparent that the specific illustrations shown above have beengiven by way of illustration and not by wa of limitation and that thefabrics above described are subjected to wide variation and modificationwithout departing from the scope or intent of the present invention; allof which variations and modifications are to be included within thescope of the present invention.

What is claimed is: A woven fabric, having a warp consisting ofvinylidene chloride threads having a diameter of 0.01" to 0.012" andrayon threads of 900 to 1100 deniers, said warp having 8 ends of rayon 4to 4 ends of vinylidene chloride threads as alternating groups ofthreads and a filling consisting of vinylidene chloride thread having adiameter of 0.01" to 0.012.
